This is a starting point for Rust solutions to the "Build your own Interpreter" Challenge.

This challenge follows the book Crafting Interpreters by Robert Nystrom.

In this challenge you'll build an interpreter for Lox, a simple scripting language. Along the way, you'll learn about tokenization, ASTs, tree-walk interpreters and more.

Before starting this challenge, make sure you've read the "Welcome" part of the book that contains these chapters:

• Introduction (chapter 1)
• A Map of the Territory (chapter 2)
• The Lox Language (chapter 3)

These chapters don't involve writing code, so they won't be covered in this challenge. This challenge will start from chapter 4, Scanning.

Note: If you're viewing this repo on GitHub, head over to codecrafters.io to try the challenge.

Passing the first stage

The entry point for your program is in src/main.rs. Study and uncomment the relevant code, and push your changes to pass the first stage:

git add .
git commit -m "pass 1st stage" # any msg
git push origin master

Time to move on to the next stage!

Stage 2 & beyond

Note: This section is for stages 2 and beyond.

1. Ensure you have cargo (1.80) installed locally
2. Run ./your_program.sh to run your program, which is implemented in src/main.rs. This command compiles your Rust project, so it might be slow the first time you run it. Subsequent runs will be fast.
3. Commit your changes and run git push origin master to submit your solution to CodeCrafters. Test output will be streamed to your terminal.
